CHEMICAL FIRE-EXTINGUISHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 409,038, dated August 13, 1889.

Application filed May 15,1889. Serial No. 310,864. (No model.) Patentedin England December 20,1887, No. 17,487; in France September 21, 1888, No. 193,120, and in Belgium September 22, 1888, No. 83,353.

To @ZZ whom t may concern.-

Be it known that I, JAMES I-IASLAM, chemical tire-engine manufacturer, of Bury Road, Tonge, near Bolton, in the county of Lancaster, England, have invented new and useful Improvements in Chemical Fire-Extinguishing Apparatus, (for which I have obtained patents in Great Britain, No. 17 ,487 December 20, 1887; France, No. 193,120,l September 2l, 1888, and Belgium, No. 83,350, September 22, 1888,) of which the following is a specification.

This invention relates to improvements in what are known as chemical fire-extinguishers, in which a vessel containing water in solution with a carbonate or-alkaline compound and a bottle containing acid are employed; and it consists in providing means for effectually and readily charging the apparatus and breaking the said bottle, so as to mix the acid with the water.

Figure 1 is a sectional elevation of the upper part of my improved chemical iire-extinguisher. Fig. 2 is a side view of Fig. 1;

and Fig. 8 is a sectional plan through line E F in Fig. 1, showing segmental ribs.

A is the case of the extinguisher, to which is secured the nozzle B, provided with the elongated end O, to operate against the ring Z in the metallic ring U, attached to the swiveling lid or cover D. The outside'of the nozzle B is provided with the segmental ribs T. The swivelin g lid or cover D is fitted with the ring U, provided with the recess or cavity X to receive the ring Z. The ring U is secured to the lid or cover D by the screwed stem Y and nut K2. The lower end of the lid or cover D is provided with the segmental ribs V, by which the same is securely fastened when swiveled under the segmental ribs T on the nozzle B. The segmental ribs T are tapered, as shown in Fig. 2, so that when the ribs V on the lid or cover D are swiveled under the same an increased pressure is imparted to the joint-ring Z. Immediately pressure is imparted to the joint-ring Z it becomes stationary along with the ring U, the latter allowing the lid or cover D to swivel round its outer surface. In the ring Z is mounted the spindle G, carrying the disk H, for the purpose of breaking the bottle E by. striking the knob .l on the spindle or stem G.

lVha-t I claim as my invention, and desire to secure by Letters Patent, is-

A chemical nre-extinguisher consisting of an alkali-vessel containing an acid-bottle an d having a nozzle at its top provided with lateral ribs, a swiveled cover having a central orifice and provided with ribs to engage the ribs on the nozzle, a metallic ring having a cavity, and a tubular stem rising through the orifice in the cover, a joint-ring arranged in said cavity and resting on the nozzle, and a vspindle extending through the tubular stem and the joint-ring and having a disk below the latter, substantially as described.

1n testimony whereof l a'l'iix my signature in presence of two witnesses. i
